The LCM of 627,720,646,660 is 2558160.
Find LCM of 627,720,646,660 with Prime Factorization
| 2 | 627, 720, 646, 660 |
| 2 | 627, 360, 323, 330 |
| 3 | 627, 180, 323, 165 |
| 5 | 209, 60, 323, 55 |
| 11 | 209, 12, 323, 11 |
| 19 | 19, 12, 323, 1 |
| 1, 12, 17, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 11 x 19 x 1 x 12 x 17 x 1 = 2558160
Therefore, the lowest common multiple of 627,720,646,660 is 2558160.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
627 x 720 x 646 x 660 = 192475958400
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
627 : 1, 3, 11, 19, 33, 57, 209, 627
720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720
646 : 1, 2, 17, 19, 34, 38, 323, 646
660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 627,720,646,660, is 1.
Now, the common factors can be found like this.
627:3x 11x 19
720:2x 2x 2x 2x 3x 3x 5
646:2x 17x 19
660:2x 2x 3x 5x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 3x 3x 5x 11x 19 = 75240
Therefore, the value for common factors is 75240.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 192475958400/(1x75240)
LCM = 192475958400/75240
LCM = 2558160
Thus, we can understand that the LCM of 627,720,646,660 is 2558160.
